Abstract
The utility model discloses a motor air-cooling structure, it comprises the axial ventilation structure and the radial exhaust structure of looks UNICOM. The axial ventilation structure consists of a stator, a rotor and a rear end cover which are assembled by a shell, and the rear end cover is provided with an axial direction. The radial air exhaust structure is contained in a front end cover, the front end cover is a double-flange component, the axial outward protruding part at the right end of the middle part of the left flange is a front bearing seat, the right flange is annular, the left flange and the right flange are axially connected into a whole by uniformly distributed radial partition plates, and spaces between the radial partition plates are communicated with an inner hole of the right flange to form the radial air exhaust structure. When the motor rotates, air is sucked from the axial through hole of the rear end cover and is sequentially subjected to heat exchange and discharged from the radial exhaust structure of the front end cover. The utility model discloses radial air exit sectional area is big, and the volume of airing exhaust is big, and the accessible of airing exhaust, the motor cooling is effectual, is particularly suitable for making high-power three-phase asynchronous motor's air-cooled structure.
Description
Technical field
The utility model relates to a kind of air-cooled structure of motor air-cooled structure, particularly threephase asynchronous.
Background technology
In motor when rotation,, because of power conversion and mechanical friction all produce some heats, these heats be if can not get timely eliminating will be accumulated as evil, easily cause motor Yin Wendu too high and damage.Commercially available motor, particularly market application quantity maximum threephase asynchronous all be provided with necessary air-cooled structure.Threephase asynchronous tradition air-cooled structure is to link up housing inner chamber air duct by the axially extending bore that front and rear cover is provided with to form, rotor when rotation the axially extending bore inspiration outside air from the tegmental wall of rear end, cold relatively air stream flow to front-end bearing pedestal from stator and housing mating groove, axially extending bore from front end housing flows out again, moving air heat exchanger effectiveness height helps the motor cooling.But the axial ventilation bore of prior art is little, and air outlet is in the face of corollary equipment, and air draft is not smooth, and cooling-down effect is undesirable.Especially high-power or at full capacity motor is bigger because of caloric value, the axial air-cooled structure of prior art can not satisfy the heat elimination and cooling requirement, causes motor Yin Wendu too high and accident that burn out happens occasionally thus.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, provides that a kind of simple in structure, ventilating opening sectional area is big, the motor air-cooled structure of good cooling effect.
The utility model is achieved through the following technical solutions technical goal.
The motor air-cooled structure, it comprises the axial ventilation structure that links in the motor and air discharge structure radially.Described axial ventilation structure is made up of housing equipped stator, rotor and rear end cap, and rear end cap is provided with axially extending bore.Its improvements are: described radially air discharge structure is located in the front end housing, front end housing is two flange components, the left side axial male part of flange middle part right-hand member is a front-end bearing pedestal, the right side flange is an annular, axially linked into an integrated entity by uniform radially dividing plate between the left and right sides flange, radially the space communicates with right side flange endoporus and constitutes radially air discharge structure between the dividing plate.
The front end housing of two flange arrangements connects the left and right sides flange by uniform radially dividing plate and forms, and space and right side flange endoporus are linked up and constituted radially air discharge structure between the dividing plate.Radially air discharge structure and axial ventilation structure that front end housing contains link.
The utility model compared with prior art has following good effect:
1, radially air discharge structure is simple, easy to manufacture;
2, radially air draft is accessible, and air draft is unimpeded, and the hot-air that helps discharging leaves.
3, radially the exhaust outlet sectional area is big, and exhaust air rate is big, the motor good cooling effect;
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Motor air-cooled structure shown in the drawings, it comprises the axial ventilation structure that links in the motor and air discharge structure radially.Described axial ventilation structure is made up of housing 3 equipped stator 2, rotor 4 and rear end caps 5, and rear end cap 5 is provided with axially extending bore 5.1, and this hole is an air inlet.Described radially air discharge structure is located in the front end housing 1, front end housing 1 is two flange components, the left side axial male part of flange middle part right-hand member is a front-end bearing pedestal, the right side flange is an annular, axially linked into an integrated entity by uniform radially dividing plate 1.1 between the left and right sides flange, radially the space communicates with right side flange endoporus and constitutes radially air discharge structure between the dividing plate 1.1.In motor when rotation, suck outside airs from the axially extending bore 5.1 of rear end cap 5, relatively cold air from after do heat exchange with stator 2, rotor 4, housing 3 and front end housing 1 respectively forward, the radially air discharge structure that is provided with from front end housing 1 is discharged again.Radially the exhaust outlet sectional area is big owing to the utility model, and exhaust air rate is big, the motor good cooling effect.In addition, radially air draft is accessible, and air draft is unimpeded, and the hot-air that helps discharging leaves.
